Upcoming job interview

Hello r/healthinspector, I have an interview coming up this Thursday for a job as a Public Health Specialist I (Oklahoma's term for health inspector) and was curious if anyone could offer me some advice. I've read through a lot of the posts here and gotten some good advice, I just don't know what to expect from the interview; what kind of questions are asked, what questions they expect to be asked by me, etc.

A little background about myself: I have a degree in science (it's a broad science degree, not highly specialized in one field, but I have bio, chem, physics, and geology classes on my transcript) I have worked as a restaurant manager, so I have some experience with HACCP and other food safety related things. But I'm really excited for the opportunity of getting an interview and want to be prepared for it. Any help would be greatly appreciated.
